VMware licenses software on a per-populated-physical-CPU-socket basis (not physical CPU cores or virtual CPUs or virtual CPU cores). Each populated CPU socket per server requires a VMware license (with VMware product and version that is supported by Cisco UC).

+

For UC on UCS (whether specs-based or Tested Reference Configuration), VMware vSphere ESXi and vCenter may be either customer-provided or purchased from Cisco.

-

While VMware ESXi is mandatory for UC to run on UCS servers, customers may purchase this license from any of the following sources:

+

For specs-based with HP/IBM servers, all VMware software must be customer-provided and may not be purchased from Cisco.

-

:*From Cisco, as a preset “per-server” Cisco Collaboration part number. This part number is separate from server hardware part numbers. You can use the same part number for Cisco UCS B-Series and C‑Series deployments. Note that for the Cisco UCS B-Series, you need to add this part number to a group of data center part numbers ordered through the Netformx DesignXpert ordering tool UCS Advisor. Only VMware vSphere ESXi 4 Standard Edition is available via this option. The part number is “hard-coded” for two CPU sockets (no more, no less) and one year service subscription (no multi-year or auto-renewals).

Cisco provides two purchase options for VMware vSphere ESXi:

-

:*From Cisco, as an option under a build-to-order “per CPU socket” data center part number for the server: Note that for the Cisco UCS B-Series, you must order this option through the Netformx DesignXpert ordering tool UCS Advisor. Only VMware Advanced, Enterprise or Enterprise Plus Editions are available via this option. One year and three year service subscription options are available.

+

:*As an option under a build-to-order data center part number for the UCS server: Note that for the Cisco UCS B-Series, you must order this option through the Netformx DesignXpert ordering tool UCS Advisor.

-

:*From VMware directly or other 3rd-party: With this option, you can order any VMware vSphere ESXi 4 Edition you want, as well as take advantage of any existing customer licensing arrangement with VMware (such as a site or enterprise license).

+

::* For vSphere 4.1, licenses are sold on a per-populated-physical-CPU-socket basis (not physical CPU cores or virtual CPUs or virtual CPU cores). Each populated CPU socket per physical server requires a VMware license and a required service contract. Only Advanced, Enterprise and Enterprise Plus Editions are available, and only with one-year or three-year service subscription options.

Presales Design Considerations

Mixed deployments of virtual, nonvirtual, Cisco-provided, and customer-provided servers are supported provided you follow all rules listed below for sizing UC applications and sizing UC hardware. Use general requirements in UC application design; for example, do not make a backup node smaller than a primary node, and do not make a Publisher smaller than a Subscriber.

Follow the coresidency policy in Sizing Guidelinesto determine which OVAs can share physical servers. Which OVAs "should" share a physical server depends on customer placement logic, which includes but is not limited to considerations for geographic distribution, minimizing server footprint, server/site redundancy, security domains, change management, service level agreements and assessed business criticality of the individual UC apps.

Verify alignment of virtualization support details (such as supported hardware or VMware features). These details may vary based on each UC application. Because UC applications share physical resources, be sure to verify alignment of these details for all UC applications in your deployment--particularly for UC applications that share a physical server.

Sizing Shared Storage (SAN/NAS)

Procurement Considerations

The following sections describe purchasing options for the various components of Virtualization of Cisco Unified Communications.

Purchasing Cisco Unified Communications Applications

There is no change to how UC applications are purchased. Cisco User Connect Licensing, Cisco Unified Workspace Licensing and Cisco UC Software Subscription are all the same for both virtualized and nonvirtualized deployments.

Purchasing the Required VMware Software

For UC on UCS (whether specs-based or Tested Reference Configuration), VMware vSphere ESXi and vCenter may be either customer-provided or purchased from Cisco.

For specs-based with HP/IBM servers, all VMware software must be customer-provided and may not be purchased from Cisco.

Cisco provides two purchase options for VMware vSphere ESXi:

As an option under a build-to-order data center part number for the UCS server: Note that for the Cisco UCS B-Series, you must order this option through the Netformx DesignXpert ordering tool UCS Advisor.

For vSphere 4.1, licenses are sold on a per-populated-physical-CPU-socket basis (not physical CPU cores or virtual CPUs or virtual CPU cores). Each populated CPU socket per physical server requires a VMware license and a required service contract. Only Advanced, Enterprise and Enterprise Plus Editions are available, and only with one-year or three-year service subscription options. VMware licensing rules must be followed to determine quantities and feature editions - see details on VMware's web site here: https://www.vmware.com/files/pdf/vsphere_pricing.pdf .

Cisco does not resell vSphere 5.0 at this time.

Preset “per-server” Cisco Collaboration part number. This part number is separate from server hardware part numbers. You can use the same part number for Cisco UCS B-Series and C-Series deployments. Note that for the Cisco UCS B-Series, you must add this part number to a group of data center part numbers ordered through the Netformx DesignXpert ordering tool UCS Advisor. There are three options:

vSphere ESXi 4.1 Standard Edition, limited to two CPU sockets (no more, no less) and only with one-year service subscription (no multiyear or auto-renewals).

Cisco UC Virtualization Hypervisor 4.1, only available with Business Edition 6000 and with limited hardware/software deployment options - click here for details.

Cisco UC Virtualization Foundation 4.1, for use only with Business Edition 6000 and UC on UCS, and with limited hardware/software deployment options - click here for details.

For guidance on supported VMware products, versions and features, and which vSphere Edition to buy for UC, see VMware requirements. If you are not buying one of the preset Cisco Collaboration part numbers for vSphere, then follow VMware licensing rules at https://www.vmware.com/files/pdf/vsphere_pricing.pdf to determine required Edition and license quantities.

Please keep the following in mind when purchasing VMware from Cisco:

A vSphere license purchased from Cisco entitles both ESX and ESXi, but remember that UC only supports ESXi.

A vSphere 4 license purchased from Cisco entitles either 4.0 or 4.1. License activation at vmware.com will be for latest version unless you explicitly request a downgrade. For version compatibility among VMware products, see the VMware Product Interoperability Matrix.

VMware vCenter is mandatory for deployments on Specs-based Hardware Support. VMware vCenter is optional for deployments on Tested Reference Configurations.

VMware.com provides Cisco-specific VMware builds for certain UCS servers. These UCS-specific builds are usually not required for UC on UCS, and the regular "off-the-shelf" builds of VMware are fine. Consult your server documentation to see which one you should use.

Purchasing Virtualization Hardware

Cisco Unified Computing System (UCS) Servers

Cisco UCS servers may be purchased through the following options:

Certain Tested Reference Configurations of Cisco UCS servers may be purchased as a single Cisco Collaboration part number. This purchase option supports only a single fixed-server configuration with no parts substitutions supported. For the Cisco UCS B200 it does not include any other components such as blade-server chassis, fabric extenders, or fabric interconnect switches (a certified Cisco channel partner must order these components using the Netformx DesignXpert ordering tool UCS Advisor). This "single SKU" option provides simplicity of ordering for deployments that are predominantly Cisco Unified Communications software. Note that some supported tested reference configurations, such as Cisco UCS C210 M2 Tested Reference Configuration 2, are not offered through this procurement option because they are used only for design guidance with Specification-Based Hardware Support. For mapping of Tested Reference Configurations to lists of equivalent Cisco Data Center part numbers, see http://www.cisco.com/en/US/prod/collateral/voicesw/ps6790/ps5748/ps378/solution_overview_c22-597556.html.

Any Cisco UCS that is deployed as a Tested Reference Configuration or that uses Specification-Based Hardware Support may be purchased as a build-to-order set of "a la carte" Cisco Data Center part numbers. This option supports all Cisco Unified Computing System components, and for UC apps that support Specification-Based Hardware Support provides a broader range of server and part options. A certified Cisco channel partner must order from Dynamic Configuration Tool (for UCS C-Series) or the Netformx DesignXpert ordering tool UCS Advisor (for UCS B-Series). This option is appropriate for mixed software deployments in which the customer wants something different from the tested reference configurations that are offered as single Cisco Collaboration SKUs.

Cisco field and channel partners may also consult the "UC on UCS" chapter of the User Connect Licensing Ordering Guide.

Third-Party Servers

Shared Storage and Network Access Hardware

Shared storage arrays (for supported SAN or NAS deployments) are customer-provided and are not purchased from Cisco. Network hardware for LAN and storage access may be Cisco-provided or third-party-provided depending on deployment.

Key Differences Between Appliances and Virtualization of Cisco Unified Communications

Deployments on Cisco 7800 Series Media Convergence Servers that are shifting to virtualization should prepare for the following:

Virtualization of Cisco Unified Communications is "not an appliance." You must independently configure, manage, and monitor the hardware, VMware software, and virtualized UC applications.

Higher level of expertise with server administration, VMware vSphere/vCenter administration, and storage administration is expected from whoever is managing the UC deployment. This expectation is more for deployments of Specification-Based Hardware Support and UC on UCS B-Series than for UC on UCS C-Series Tested Reference Configurations.

If you are using Shared Storage (SAN or NAS), be aware that it is a critical solution component and if improperly configured, monitored, or managed will cause significant performance and availability issues for UC apps. Ensure that whoever is managing the UC deployment is experienced and proficient with storage management.

Adhere to all licensing requirements for virtualized UC apps. For example, license keys may be different when virtualized than they are on appliances.

UC application features that are dependent on physical USB ports are not supported. See the required UC Application documentation for alternatives and workarounds.

Considerations for Cisco TAC Support

This section is for convenience and illustration purposes only, and does not supersede any master support agreements or other support documents between Cisco and its partners/customers.

If you purchased your solution components from Cisco and have a service contract with Cisco, then Cisco TAC accepts the first call for virtualization issues, coordinates triage, and automatically escalates the issue to other vendors covered by Cisco service contracts as required.

If your solution components are self-sourced, then Cisco TAC does not take the first call, nor does Cisco provide triage coordination or escalation. In these cases, you may need to directly engage with your component vendors to escalate an issue and/or coordinate triage with Cisco TAC.

The following table identifies who takes the first call for each solution component.

Note:

These support demarcations are similar to the appliance hardware demarcations provide by Cisco versus customer self-sourced.
